Application filed January 23, 1915. Serial No. 4,011.

To all w/om ity/2mg concern.'

Be it known that I, THOMAS Cox, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and'useful Improvements in \Hangers for Polished-Rod Adjusters for lVells; and l do declare the following to bea full, clear, and exact description of the invention7 such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and ligures` of reference marked thereon, which form a part of this specification.

My invention relates to hangers for polished-rod adjusters for wells.

.it has for its object torprovide a hanger which can be readily and easily placed and remove-d from the walking beam and in which the lines of force will be contained or fall within the hanger as hereinafter indica-ted so that the hanger will not tilt in the movements of the beam, and in which furthermore, the adjuster rods can be lifted from off the hanger and replaced in position without the necessity of climbing up to the beam for the purpose.

To the accomplishment of. the foregoing and suchk other objects as may hereinafter appear the invention consists in the features hereinafter described and then sought to be clearly defined by the claims, reference being had to the accompanying drawing forming a part hereof, and in which Figure l is a side view of a walking beam with the improved hanger applied; `Fig. 2 is an end view of the same parts; F ig. 8 is a cross-section on the line 3.-3 of Fig. 1.

In the drawing the hanger is illustrated as an open frame composed of oppositely disposed sideebars l connected together at the top by horizontally disposed bars 2, and provided at the lower end or bottom with a casting 3 from which depends an open faced hook 4. The frame converges, front and rear, from top to bottom, so that a relatively broad bearing for the frame on the beam is afforded, and the `iournal-bearh ing of the hook is so disposed with relation to the frame that when the polished-rod adjuster is suspended from the hook the lines of force will fall within the feet of the frame and the frame will rest firmly on' the beam without tilting in the movement the frame. or

`ing in the of the beam. It will therefore be observed that material features of the hanger are that the frame converges, front and rear, from top to bottom Yand that the hook has its journal-bearing so disposed in relation to the frame that a line drawn centrally and vertically through the journal-bearing will pass centrally and vertically between the front and rear of the frame, and thus cause the lines of force to fall within theV feet of centrally through the frame. so that the frame will be prevented from tiltrocking or oscillation of the walking beam to which the hanger is attached. The frame is preferably formed of angle-bars with the parts riveted together where they intersect or join. and the casting 3 is riveted or bolted to the angle-irons 5 which unite the lower ends of the upright bars 1 of the hanger frame. The casting and its pendant hook is preferably formed with oil ducts 6 for lubricating the pin 7 by which the polished rod holder 8 carrying the polished-rod 9 is suspended from the hook. i

In practice, the hanger-frame is slipped over the end of thel walking' beam 10 and adjusted so that with the beam 10 in the central or middle of its walking stroke the vertical line of the pin 7 will be substantially horizontal with the beam center-bearing 11 above the supporting post 12 and vertically over the well 'polished rod as indicated in Fig. 1 of the drawing, and thus the smallest deviation of the vertical arc takes place either aboveor below center in the movement of the beam, and as the movement of the beam is usually one foot each way the polished rod is caused to travel practically ina vertical line, and bending and wearing of the rod., and cutting out of the packing and. stulifing box head is practically prevented.

lf desired a hard wood block 13 may be y interposed between the beam and the top of the hanger-frame as indicated in F ig. 1 of the drawing.

lt will be observed that no permanent fastening of the hanger-frame to the beam is necessary as the broad bearing afforded by the relatively wide top of the frame and the line of forces passing between the feet of the frame by reason of the position of the suspending hook cause the hanger to rest firmly on the beam and without tilting 1 Copies of this patentmay be obtained'for in the movements Voi' the beam. rIhis also enables the hanger-frame to be readily placed in position and to be removed When necessary or desirable. It Will also be observed that the open face hook beneath the hanger enables the polished rod vadjuster and its holder to be attached to the hanger and removed therefrom when necessary by manipulation 'from the ground Without the necessity or' climbing up to the beam for the purpose.

The suspension hook may have a closed eye instead of open face to form the journalbearing and a loose pin passed through the eye and adjuster to pivotally suspend the latter.

Having described my invention and set 'forth its merits, What l claim is 1. The hanger for well polished rod adjuster consisting or' an open frame adapted to be slipped over the end of a Walkingbeam, said frame converging from top to bottom and provided at the bottom with a suspension hoo 2. The hanger Jfor Well polished rod adjuster consisting of an open frame adapted to receive the end of a Walking-beam and to rest freely upon the'beam and provided at its lower end with an opendiaced hook 3. The hanger for well having its journal-bearing face substans '30 tially coincident with a line passing centrally and vertically through the hangerframe.

j polished rod adjuster consisting of an open frame formed of upright side bars converging, front and rear, from top to bottom, horizontally disposed bars connecting the ends of the side bars, and a casting connected to the lovver end of the frame and provided with a journal-bearing for the suspension of the polished rod adjuster'.

' 4L. The hanger for Well polished rod adjuster consisting` of a member for attachment to a Walking beam, and a pendant Jfrom said member formed With a journalbearing face disposed substantially coincident with a line passing centrally and vertically through said member and hori zontally through the center-bearing of the beam when the beam is in its horizontal position.
